Legionella Risk Assesment

A Legionella risk assessment is exactly that – an assessment of the Legionella risks associated with a water system on site. It is an important part of water treatment practise as many legionella outbreaks have been the result of poor water systems management. A risk assessment also outlines protocol which should reduce said risks. Having a risk assessment also helps firms ensure that they are compliant with ACoP L8 standards.

A risk assessment should include the following:

The Inspection of all tanks to ensure they are compliant with all relevant legislation.

The Inspection of water heaters and calorifiers to ensure they comply with all relevant legislation.

The Inspection of water distribution systems to ensure they comply with all relevant legislation.

Temperatures to be taken from around the site to ensure they are not at a level to promote the growth of bacteria.

The production of an Asset register

Digital photographs of the main pieces of the plants water system.

Schematics of all main pieces of a plant’s system

A Responsibility Structure so that all involved know the level of responsibility they have for the up keep and maintenance of the water system including chemical treatment.

Recommendations that include the remedial work that is required to bring the system within the guidelines as set out in the ACOP L8 document
